Hi List,

i have two questions:

1.  As per TLS 1.2 RFC,  CCS message is 1 byte with value 1. This should be
encrypted with current cipher algorithm. My questions: when i captured
packet, i could see that packet is not encrypted ( i could see value one).

2.  TLS CCS packet is not encrypted with block cipher algorithms ? current
cipher algorith is AES256-SHA256 in my case. but total size of CCS record is
6 bytes.
